On my IO-360 M1B with WW200 prop I will occasionally get a strong kickback when I first engage the starter. When I hit the starter button again it has always spun the engine fine. I recently found that the ring gear had several teeth damaged so I had to replace it. I thought it was an ignition problem causing the kickback but after having V40 update on my PMags and verifying they are indeed firing after TDC I am now looking for other possibilities. The starter goes up against a compression stroke and kicks back then the next try spins through it. Has anyone experienced this issue?
